Fetal Macrosomia


Consider 37-39 week ultrasound for EFW (estimated fetal weight) if suspected macrosomia:
  • DM particularly if pregestational/ A2/ poor control
  • Obesity/elevated maternal BMI
  • Measuring large on fundal height
  • Subjective maternal sense of large baby

To improve accuracy it is best to get EFW sonogram >37-39 wks EGA to avoid need for extrapolation of growth from time of ultrasound to presentation to L&D.

Induction of labor is not indicated for suspected macrosomia
-only increases cesarean delivery rate with no improvement in outcomes

Offer primary section if >5000gm EFW in non diabetic mother, > 4500gm in DM or GDM mother to decrease risk of fetal birth injury

If prior fetal birth injury or difficult delivery, consider consult with OB staff for route of delivery even if EFW below the 5000/4500gm standards listed above
